JB 4.1.2 on this phone is very nice. Upgraded easily and did not even did a reset of the phone. Everything is better, even battery. Camera is improved and you can now zoom while playing video !! Feels like an S4 now...Using Holo Launcher HD Plus. Will keep it for a long time...No need for S3 or S4. Maybe S5 if it has stereo speakers.

The security system of has to be little flexible as I had very bad experience when I forgot my password and in hurry tried many times to open the lock final the it permanently locked and need to reset loosing all my valuable data at an authorised Samsung service point . The manufacturer should provide some solution to recover data at this situation ..

I just love smart stay, working perfectly.
